Percentage error . . . Didn't we just have a discussion of this? Are
you talking about the size of the students' error bars, or the
deviation from the "accepted value." I always ask my students, if the
"percentage error" is the difference between their result and the
"accepted" value, how did Millikan calculate his percentage error?
I've actually had a few answer me, "The same way we do."

Those are the days I head straight for the bar after work.

Never ask someone what computer they use. If they use a Mac, they
will tell you. If not, why embarrass them?
